What kind of batteries are you using in the E-Maxx?
Do you have a wheely bar for the E-Maxx?
With a set of LiPos and a wheely bar, I'd put my money on the E-Maxx.

um...say a nice pack of 6 cells with a wheelie bar.

When it comes to acceleration, the 16.8 E-Maxx with good 7-cell packs (or LiPos) will embarrass the Revo up until about 30-35mph. Give it enough space and the Revo will eek past the E-Maxx with its higher top speed...so I don't know. Could be close in a 200ft race, but I'd like to bet on the E.

Of course, strap a good brushless system in the E and it'd just destroy the Revo at any speed.;)

Well, if you can put nice Lipos in the Emaxx, I say you get to put at LEAST 30% nitro in the Revo. Tighten up the slipper clutch a little, put a .18TM in, and an M2C aluminum clutch, and the Revo would smoke it. A brushless Emaxx would tear even a BB Revo a new one, though *shame* :D.

Castle has been hitting 60 with their E's, but that's because they were testing their new MMM, using a Neu motor and probably pushing the ESC's limit (6s of lipo power).

60mph is insane for any car, but for an 8-10lbs maxx, its insane. Personally I can't wait for it to come out.

holy cow! ok thats the setup imma get then. i wonder when the mmm is suppose to come out though... thats too fast for me though. i just wanna be rolling at 40mph. ill be happy with going 40mph with my big o imex jumbo tires and 7 cell packs.

A novak HV-Maxx 4.5 on 14 cells will hit over 40.

I have a brushless stampede that will do 50 if you let it REALLY top out, even though its really practical top speed is probably 40-45 range. The thing is ridiculous though because, even though I've had cars/trucks faster in the past (nitro tc3, r40, even my bolink digger and some other nitro vehicles), the darn thing has SO MUCH TORQUE at top end that it just pulls and pulls and pulls. It may not be going as fast as you want to brag about, but 40 with a brushless (ESPECIALLY sensorless: i.e. Mamba Max/Mamba Monster) is NOT the same as 40 with a tall gear on a brushed motor.

The real benefit of brushless for monster trucks is the plethora of torque they offer. With 26mm hubs and large 40-series rims and tires, and some running 3s lipo packs, our trucks are becoming heavy (I know my TXT has over four pounds in the wheels alone!). So add brushless, and it has such an easy time developing torque (and it's so efficient) that run times are great too. However, speed can be bad for these trucks. Even around 20mph (maybe) my TXT is not perfectly stable. The Emaxx is a great chassis, so 40 is doable with heavier springs and oil, but still. May as well gear for 35-40mph and get wild 20-30 min run time if you can.

yups im going brushless for sure then. im surprised i can even hit 40 with these huge tires..here are my tires and wheels

hey 7urbo, why didnt u get 23mm hex? is the standard not good enough? dont u have to get 23mm wheels now? and im sure u got metal hex wont that strip the plastic from the wheels? im new to lipos...so do i only need one lipo battery instead of the normal two nimh packs? can someone send me a link to one good 3c lipo battery so i can know the price and how it looks like so i know. oh. can any esc take lipo batteries...or only brushless escs? for example...a novak tc2. all i know is that you need a special charger to charge lipos.

thanks

You need 2 lipos still. You'll want to run dual 2s packs for a maxx. 2s~12 cells nimh. Any ESC can handle lipos, but its a good idea to run a low voltage cutoff so you don't kill them by over discharging them.

Standard hex's aren't as strong and strip under heavy running. Its worth it to switch to 23mm.....theres a huge selection of wheels for 23mm and you can always switch back to use your old 14mm wheels

Well, I primarily chose to go with the 23mm hex size to accomodate the Proline 23mm beadlock rims, which allow me to bolt on (not glue and eventually lose) 4 rims and 4 tires. Now I have a permanent set of rims, and I can swap out a new set of tires whenever I want. It is true that they 23mm hex surface affords better durability and torque capacity so you are far less likely to strip out even in brushless applications and off roading. I also chose them because they widen the track width of the TXT by about 1.5 inches total for better appearance (I can be honest!) and better stability and traction. Because I have a Tamiya TXT and Proline don't offer a conversion, I went to RC4wd.com for my adaptors. They are very well-made.

Downsides? The adaptors from RC4wd are expensive at $60, but the ones from Proline are more reasonable at about $15 per pair. Also, for racing applications like my small-block Revo, a 23mm hex upgrade adds unnecessary weight without required improvements. For a brushless bashing truck though, you'll appreciate it. Do yourself a favor and grab the beadlock Commando rims :).

Well I have a new Revo 3.3 and my daughter has a new E-Maxx with two 8000mah maxamp LiPo batteries and the Revo is way faster. In fact I am trying to get her to switch to nitro she hates the noise and smell. I only get about 45 mins to a hour on her batteries and I have to recharge for 2 hours. I am new to this hobbie and now seeing the advantage to nitro just fill up and go for hours. I love it. The E-Maxx is nice for climbing and running in my neighborhood. :D

ok ill maybe switch if or after my 14mm hex strips. but ill keep those tires and rims in mind. yea i know the 3.3 revo will win for sure.

Trust me, you don't want to wait for it to happen, it'll happen at the worst possible time.

The stock E-Maxx on dual lipos is going to have great run time but not much top speed. If you give each truck the most expensive things money can buy, the E-Maxx will be much faster.

i looked at them 23 mm beadlock commandos and they still have the plastic inside of rim. so which part are you talking about that will strip with the 14mm hex's? because the stock 3905 emaxx comes with metal 14mm hexs now so i dont think that will strip ...maybe the plastic part of the rim where the hex goes..but then i think the plastic on the rim of the bead lock rims will strip as welll where the 23mm hex goes. am i wrong?

Of course they have plastic inside the rim, all plastic rims do, thats why we call them plastic rims.

The bigger 23mm hexes are much heavier duty, end of story. Its still stronger than 14mm metal hexes.

You can use the stock 14mm as long as you like, but companies don't make money selling 23mm hex adaptors if 14mm metal ones are perfectly fine for high power situations. As you get into higher torque set ups, you'll want them. I'm not forcing you to, but its a good idea to invest sooner and have one less thing to worry about.

Also, 45 min to an hour is huge...like scary huge. Under normal racing conditions a nice NIMH pack might last 7 minutes with the latest stuff. When I get 20 minutes I'm absolutely shocked with my 6000 packs on a B4.

blueb8llz, the main issue with 'stripped hexes' in high-torque brushless applications is never whether the actual hex part which fits onto the axle strips, rather the plastic rim hex which accepts the individual hex piece strips. It will happen rather quickly and is very inconvenient because you can never really fix it. The reason the larger 23mm hex is more durable is because the larger hex (the blue aluminum hexagon) is so much larger that the surface area is significantly larger. This applies to the interior wheel hex in the rim as well. With the larger (significantly) surface area comes a great increase in torque capacity. I guarantee you will never strip those 23mm hexes out, regardless of whether you run the stock Titans with lipos, or even a dual HV-Maxx on dual 3S3P lipo packs. The surface area present is just so much larger. Also, they are better machined and the rims are better formed (tighter tolerances) so fitment is nicer and the tendency to strip is completely negated. Plus they are blue! *harcore*

ahh...ok now it makes more sense! ok , so do them commando rims make your truck wider? i think i read that they are offset. i want some wheels/tires that will make my emaxx wider. do you know how wide the tire after installing them onto the rims? and how tall? what tires did you get. i think i like the moabs. can you point me to the right direction so i can choose from 23mm tires that will fit onto the commandos. i want tires that are almost 4.5 inches in width, and 6 inches tall. well the width doesnt matter as much as long as these rims are making my truck wider. i typed in 23mm tires and barely anything came up??? do i need to type in 40 series tires or something.. and what does 40 series mean anyways?
sorry for the many questions. but now you guys got me very intersted in these 23 mm tires and rims. oh, what else to i need to use these tires/rims....a adapter you were saying? anything else?

qUEESttionn....oVEERLoAd???!!//?!!!!!! *zzzzzzz*

Okay, so first, the proper designation for these wheels and tires is "40-Series with 23mm hubs". The 40-series part refers to the rim diameter and the corresponding tire size, while the 23mm part refers to the hex size. Second, the rim is the part which will determine whether there is additional offset to be had (increased width), and these wheels will indeed add about 1" width to your maxx, possibly. It might be 1/2", but it will be wider.

Third, if you go with the Commando beadlock rims, you will have all the 40-series tires as your selection base (all fit). I personally chose the Mashers, which are awesome and perform best on all surfaces including asphalt or concrete, wet sufaces, rocks, mud, grass, gravel, etc. Another popular choice is, of course, the Moab, which tends to perform better on dry surfaces and nothing muddy or wet or exceedingly loose (dry packed dirt is better for the Moab than loose). There are a few choices, so go to http://www.prolineracing.com/ and go to monster truck tires to see what you like. Tower Hobbies (www.towerhobbies.com) has an awesome business, and they ship quickly.

Dimension wise, it doesn't really matter, as they are all approximately the same size as long as you don't go into the 40-series XL and narrowed beadlocks. Those are narrower rims and use taller tires, and you don't want that unless you are rock crawling, which you're not (I assume :)). So, stick with the 23mm Commando rims and 40-Series tires. You will need two sets of these: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXJGR4&P=ML to fit the rims on your axles, but aside from that you should be set. And remember that when searching for products, you search "23mm proline" for rims, and "40 series proline" for tires and rims. If you have an doubts about what you are about to order, just post it here and I can check.

perrrfect. you answered my questions in great manner hahah.. thanks man, i really do appreciate it. people are telling me mixed reviews on 14mm to 23mm adapters, so they are tryin to persway me into going 17mm. but yea. i think i like your masher tires...looks good!so i looked for 23mm proline on ebay.. theres only like 3 rims to choose from. do i have to use proline rims for proline tires?? the commandos are pretty pricey for me. i sorta just want some cheaper 23mm offset rims that will fit the mashers. i found some adapters on ebay ...used proline 23mm adapter. doesnt matter if i buy them used right..since he says excellent condition and they are aluminum so i doubt theyre stripped.

ok so i came up with my set. i want the 23mm cheyenne rims with 1/2 offset with either the 40 series masher or moab tires. those are compatible right? will my stock tires fit on the 23mm cheyenne rims? i wished the mashers were 1/2 inch wider so im less likely to roll over or flip over at high speed turns. you think with the offset rims ill never roll/flip over? thats the only reason why i like the moabs more becuase they are wider. but they are also taller so maybe its more likely to flip/roll over. but you say as for as all around terrain ...both of them should do well correct other than the moabs are too good for loose surfaces. sux cus i run on more loose surfaces such as pebbles rocks construction site type of area rather than packed dirt. desision decesion. and the moabs are sooo much more heavy too. what you think, of those two tires..which is less likely to roll/flip over at turns on high speed. i know with my wide 4.75 imex tires...i was never able to flip no matter how fast / turn i did.

7urb0_c471
02-12-2008, 08:02 PM
No no no, I said the Moabs handle worse on loose and wet terrain. However, both would work very well in general. As for rolling, the masher will be more stable, and it is just as wide as the Moab, but with both you are bound to flip if you turn too hard. Especially with the speed offered by brushless, if you turn too quickly at higher speeds you WILL flip regardless of which tires and wheels you run. You also cannot run non-40-series tires on 40-series rims.

17mm are not as good for bashing and brushless as 23mm, period. No question.

THe Cheyenne wheels are perfect and just as good, but you will sink money into that set of 4 rims and tires, and never get it back, whereas with Commandos, you get to keep the rims after the tires wear out. But money is money, we don't have infinite :). You'll be styling either way with high quality rims and tires.

Used adaptors will work.

blueb8llz
02-12-2008, 08:36 PM
since ur saying i will flip no matter what...im sorta likin the big joes now. what terrain is that good for...how those compare to the mashers/moabs. have you had experience with the big joes or heard reviews about them? and what are the spacers used for that comes with the adapters...i believe theres 16 of them for the 4 hex. some used sellers dont come with them. is it important to have those spacers?

7urb0_c471
02-12-2008, 08:48 PM
The spacers just take out some of the spacing between the hub carrier and the adaptor; they are not critical.

The Big Joes, idk, they look like they'd be good for really knarly terrain and more bashing. They look cool. Mini-TBasher55 has them, but I don't think he's run his very much. I personally love my Mashers though.

will 23mm adaptors for the revo fit my new emaxx? i know the tmaxx, lst, and mgt will fit. hmmm maybe ill try looking to see what other 40 series tires are out there, like other brands besides proline. ill be back with some ideas.
